PICKER-CHECK FOR LOOMS.

SIECIFICATION forming part of Letters Patent No. 415,753, dated November26, 1889i.

Application tiled January 23, 1889. Serial No. 297,278. (No model.)

To aZZ whom it may concern.-

Be it known that I, ROBERT WHrrEHoUsE, of the city, county, and State ofNew York, have invented a new and useful Picker-Check for Looms, ofwhich the following is a full,

clear, and exact description.

My invention relates to an improved picker check or bunter for looms,and has for its object to provide an elastic cushion capable of read-yattachment to and detachment from a loom, whereby the shock orconcussion usually sustained by the contact of the shutt-le with thepicker will be largely reduced and the shuttle-binder need not be sotightly adjusted as heretofore.

The invention consists in a picker check or bunter having' a flexiblecushion face, and in the novel construction of the said bunter, as willbe hereinafter more fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying' drawings, forming a part ofthis specification, in which similar gures of reference indicatecorresponding parts in all the views.

Figure 1 is a vertical section through t-he projecting portion of theframe-work and the shuttle-box of a loom, illustrating the position ofthe bunterY in the loom, which position is immediately to the rear ofthe picker. Fig. 2 is a side elevation of the bunter, partially brokenaway. Fig. 3 is a bottom view of the saine; and Fig. 4 is a face view ofthe said bunter, showing the cushion carried to one side.

The bunter is adapted especially to replace the one at present in almostuniversal use, which latter consists simply of pieces ot cloth ragbunched together and inserted in the pocket or projecting portion of theloom-frame in front of the picker 11, in which position my improvedpicker check or bunter is illustrated in Fig. 1.

The improved bunter consists of a frame or body 12, preferably ofgreater length than width, adapted in contour to the contour of theframe-pocket at the rear of the picker of the loom. The body-frame 12 isusually constructed with a depression 13 in the inner face, at or nearthe center, which depression, when the bunt-er is in proper position,isadapted to be in horizontal alignment with the travel ot` the picker. Inthe inner face of the bodyframe, at each side of the central depression,a recess 14 is formed, into which recesses a spring 16 is severallyvinserted, and a strip of leather 17 or other equivalent tiexiblematerial of suitable width is pivotally attached to the ends of thebody-frame and drawn tightly over the inner face of the samein contactwith the outer ends of the springs 16.

In Fig. 3 of the drawings, which is a bottom View of the bunter,ashoulder 18 is shown as centrally formed at one side ot the bodyframe,which shoulder -is not absolutely necessary in the formation of saidframe, being device into one form of loom.

l desire it to be distinctly understood that the body-frame may beconstructed either of Wood, of iron, or of other suitable material,

and that the leather strip 17, which acts as a cushion, may be replacedby a strip of canvas, rubber, or other like flexible material, and thatthe springs may be Otherwise attached to the body-frame; or other formsof spring may be employed Without departing from the spirit of theinvention. The springs 16, should they become weakened and uni-lt foruse, may be quickly removed by carrying the cushion 17 over to one sideof the frame, as sho'wn in Fig. 1i, the said cushion being pivoted forthat purpose, .whereupon the Vouter ends of the springs' will beuncovered, and they may be readily detached and replaced by others. Thecushion 17 is drawn When not in use or when in operation.

- Vhen my improved bunter is employed in connection with a loom, itpermits the weaver to use shuttles of differing weights and sizes,(which now cannot be done Without a readj ustment ot the shuttle-binden)as the shuttlc-binder will not have to be adjusted so tightly that anydifference in the size of the shuttle can affect it. lVith the old formof bunter, however, a great pressure must be brought to bear upon theshuttles by the binders, so that the shuttles have to be of equal sizein order to Work properly.

adapted only to facilitate the tit-ting of the.

suficiently tight over the springs 16 as to prevent it from Working toone side eitherl IOO 'Although I have illustrated my invention asapplied to a particular form of loom, I Wish it to be understood that itis applicable t0 any form of loom.

Having thus described my invention, I claim as new and desire to securebyLetters Patent- 1. A picker-bunter for looms, consisting' of a bodyand a spring supported cushion,

' formed of leather or its stated equivalent,

covering' one face of the-said body, substantially as shown anddescribed. l

2. As an improved article of manufacture, a picker-bunter for looms,consisting of a .body and a pivoted spring-supported cushion coveringone face of the said body, as and for the purpose speciied.

3. As an improved article of manufacture, a picker-bunter for looms,consisting of a body having a cavity in one face, a flexible cushionextending from end to end of the body over the cavity therein, andsprings between the adjacent faces of the cushion and body at oppositesides of the said cavity, substantially as shown and described.

4. As an improved article of manufact-ure, a picker-bunter forlooms,consisting of a body, a cushion pivoted to the said body at. the endsand extending over one face, and detachable springs held in contact withthe opposed faces of the cushion and the body, substantially as shownand described, and for the purpose specified.
